The Independence Centenary International Exposition was a World Expo held in Rio de Janeiro from September 7, 1922 to March 23, 1923, to celebrate the 100th anniversary of Brazil's Independence. The expo happened during the Epitácio Pessoa Administration and was regarded as an opportunity to show off Brazil's growing industries and commercial opportunities. The Expo's pavilions were constructed alongside the Rio Branco Avenue and built just for the occasion.
